Passengers with reduced mobility
To avoid problems you are strongly advised to contact the airline at least 48 hours before your trip to explain what assistance you require, when boarding or elsewhere at the airport. You cannot be denied boarding because of your reduced mobility, unless the aircraft is physically too small or there are security concerns.
Airlines do not have to provide help with eating or taking medication during a flight. If you need this type of help, for example during a longer flight, airlines might request that you be accompanied by another person.
If you have problems getting help while travelling, you should tell the airport authorities or the airline concerned.
